Isingeniso se-Swift: Izici Nezinzuzo

Informatec Digital » Ukuhlela » Isingeniso se-Swift: Izici Nezinzuzo

Ukuthuthukiswa kohlelo lokusebenza lweselula kuhlangabezane nokukhula okuphawulekayo eminyakeni yakamuva. Ngokukhula kwesidingo sezinhlelo zokusebenza ze-iOS, isidingo solimi lwesimanje nolusebenzayo lokuhlela sesivele. Ukuphendula lesi sidingo, i-Apple yethula i-Swift ngo-2014, ulimi lokuguqula uhlelo oseluthole ukuduma emphakathini wonjiniyela. Kulo mhlahlandlela ophelele sizokunikeza isingeniso se-Swift, izici zayo nezinzuzo, nokuthi ingathuthukisa kanjani indlela othuthukisa ngayo izinhlelo zokusebenza zamadivayisi we-Apple.

Isingeniso se-Swift: Izici Nezinzuzo

Yini esheshayo?

I-Swift iwulimi lokuhlela olusezingeni eliphezulu olwakhiwe yi-Apple ukuze kuthuthukiswe izinhlelo zokusebenza ze-iOS, i-macOS, i-watchOS, ne-tvOS. Yakhelwe ukuba kube lula ukuyifunda nokusebenzisa, kuyilapho ihlinzeka ngokusebenza okukhethekile nokuphepha okuqinile. I-Swift iwulimi lwesimanje lohlelo oluhlanganisa izici ezivela kwezinye izilimi ezidumile njenge-Objective-C, C#, Python, neRuby.

Izinzuzo ze-Swift

1. I-syntax enembile

Enye yezinzuzo eziyinhloko ze-Swift i-syntax yayo enembile futhi ecacile. Ulimi luklanyelwe ukuthi lube lula ukufunda nokubhala, okwenza inqubo yokuthuthukisa nokusebenzisana phakathi kwamalungu eqembu ibe lula. I-syntax ye-Swift ithonywa izilimi zokuhlela ezimbalwa, ikunikeza umuzwa ojwayelekile konjiniyela asebevele benolwazi kwezinye izilimi.

2. Ukuvikeleka Okuthuthukisiwe

I-Swift yakhelwe ngokugxila ekuvikelekeni kwekhodi. Ulimi luhlanganisa izici ezisiza ukuvimbela amaphutha avamile kanye nokuthuthukisa ukuqina kohlelo lokusebenza. Isibonelo, i-Swift isebenzisa inkomba yohlobo ukuze ihlole ngokuzenzakalelayo izinhlobo zedatha futhi ithole amaphutha ohlobo angaba khona ngesikhathi sokuhlanganiswa. Lokhu kugwema amaphutha amaningi okungenzeka ngesikhathi sokusetshenziswa kohlelo lokusebenza futhi kuthuthukisa ikhwalithi yekhodi.

3. Ukusebenza okulungiselelwe

Enye inzuzo ebalulekile yeSwift ukusebenza kwayo okuthuthukisiwe. ISwift isebenzisa injini yokwakha ye-LLVM, ethuthukisa ngokuzenzakalelayo ikhodi ukuqinisekisa ukusebenza kahle. Ulimi luphinde lusebenzise amasu okuhlanganisa athuthukile, njengokususwa kwekhodi efile kanye nokusabalala okuqhubekayo, ukunciphisa usayizi osebenzisekayo nokuthuthukisa ukusebenza kohlelo lokusebenza lonke.

4. Ukusekela kwe-Objective-C

I-Swift isekela ulimi lohlelo lwe-Objective-C, obelusetshenziswa kabanzi ekuthuthukisweni kohlelo lokusebenza lwe-iOS ne-macOS esikhathini esidlule. Lokhu kusho ukuthi onjiniyela bangasebenzisa ikhodi ye-Objective-C ekhona kumaphrojekthi we-Swift futhi ngokuphambene nalokho. Ukusekelwa kwe-Objective-C kwenza kube lula ukuguqula kancane kancane amaphrojekthi akhona ku-Swift futhi kuvumela abathuthukisi ukuthi basebenzise imitapo yolwazi ekhona nezinhlaka.

5. Ukusebenzisana namapulatifomu amaningi

Ngaphezu kokusekela i-Objective-C, i-Swift iphinde inikeze ukusebenzisana namanye amapulatifomu nobuchwepheshe. Onjiniyela bangasebenzisa i-Swift ukuthuthukisa izinhlelo zokusebenza ze-iOS, i-macOS, i-watchOS, ne-tvOS. Lokhu kuvumela amaqembu okuthuthukisa ukuthi enze izinhlelo zokusebenza ezisebenza kumadivayisi amaningi nezinkundla ngaphandle kokuthi afunde izilimi zokuhlela ezihlukile.

6. Ukuthuthukiswa okusheshayo

I-syntax ye-Swift ecacile nefushane, ehlanganiswe nokuphepha kwayo okuthuthukisiwe nokusebenza okuthuthukisiwe, inika amandla ukuthuthukiswa kohlelo lokusebenza ngokushesha. Onjiniyela bangabhala ikhodi encane ukuze bathole imiphumela efanayo, okusheshisa inqubo yokuthuthukisa futhi kunciphisa ithuba lokwethula iziphazamisi. I-Swift iphinde ihlanganise izici zesimanje, ezifana nokubamba amaphutha, imisebenzi ye-oda eliphezulu, nezandiso, ezivumela uhlelo olusebenza kahle kakhulu futhi oluvezayo.

7. Umphakathi omkhulu nokusekelwa

Kusukela yasungulwa ngo-2014, iSwift ithole umphakathi wabathuthukisi abakhuthele nababandakanyekayo emhlabeni wonke. Lo mphakathi unikela ngamalabhulali, amathuluzi, kanye nezinsiza zemfundo ezisiza abathuthukisi ukuthi bazuze kakhulu olimini. Ngaphezu kwalokho, i-Apple inikeza imibhalo eminingi kanye nezinsiza ezisemthethweni zeSwift, okwenza kube lula ukufunda nokuthuthukisa ulimi.

8. Ukuthuthukiswa okuqhubekayo nezibuyekezo ezivamile

I-Apple izibophezele ekuthuthukisweni okuqhubekayo nasekuthuthukisweni kwe-Swift. Ulimi lwenziwe ngezibuyekezo ezinkulu ezimbalwa kusukela ekukhululweni kwalo kokuqala, kwethula izici ezintsha nokuthuthukisa ukuzinza nokusebenza. Izibuyekezo ezivamile ziqinisekisa ukuthi onjiniyela bangasebenzisa izinto ezintsha zakamuva kanye nemikhuba ehamba phambili ekuthuthukisweni kohlelo lokusebenza lwe-iOS.

Imibuzo Evame Ukubuzwa Mayelana Nokuqalisa Nge-Swift

1. Uyini umehluko phakathi kwe-Swift ne-Objective-C?

I-Swift ne-Objective-C yizilimi ezimbili zokuhlela ezisetshenziselwa ukuthuthukisa izinhlelo zokusebenza ze-iOS ne-macOS. Umehluko omkhulu ulele ku-syntax nendlela yokubhekana nayo. I-Swift ine-syntax yesimanjemanje futhi emfushane uma iqhathaniswa ne-Objective-C, okwenza ikhodi ibe lula ukuyibhala nokufunda. Ukwengeza, i-Swift ivikeleke kakhulu futhi inikeza ukusebenza okuthuthukisiwe uma kuqhathaniswa ne-Objective-C.

2. Ingabe kuyadingeka ukwazi i-Objective-C ukuze ufunde i-Swift?

Cha, awudingi ukwazi i-Objective-C ukuze ufunde i-Swift. Nakuba i-Swift ihambisana ne-Objective-C futhi ungasebenzisa ikhodi ye-Objective-C kumaphrojekthi e-Swift, kungenzeka ukufunda nokuthuthukisa izinhlelo zokusebenza ze-Swift ngaphandle kolwazi lwangaphambilini lwe-Objective-C. I-Swift ulimi oluzimele futhi lungasetshenziswa ukuthuthukisa izinhlelo zokusebenza eziphelele ngaphandle kokudinga i-Objective-C.

3. Ingabe i-Swift ingeyokuthuthukiswa kohlelo lokusebenza lwe-iOS kuphela?

Cha, i-Swift ayikhawulelwe ekuthuthukisweni kohlelo lokusebenza lwe-iOS. Ngenkathi i-Swift iqalwe njengolimi lokuthuthukisa izinhlelo zokusebenza ze-iOS, ingasetshenziswa futhi ukuthuthukisa izinhlelo zokusebenza ze-macOS, watchOS, ne-tvOS. I-Swift inikeza ukusebenzisana kwe-cross-platform, okuvumela abathuthukisi ukuthi bakhe izinhlelo zokusebenza ezisebenza kumadivayisi ahlukene we-Apple nezinhlelo zokusebenza.

4. Liyini ikusasa le-Swift?

I-Swift inekusasa elithembisayo ekuthuthukisweni kohlelo lokusebenza. I-Apple iyaqhubeka nokutshala imali ekuthuthukisweni nasekuthuthukisweni kwe-Swift, okubonisa ukuzibophezela kwayo kwesikhathi eside kulolu limi. Ngaphezu kwalokho, i-Swift ithole ukuthandwa emphakathini wabathuthukisi futhi isibe yisinqumo esikhethwayo sokuthuthukiswa kohlelo lokusebenza lwe-iOS. Ngohlelo lwayo olunembile, ukuphepha okuthuthukisiwe, kanye nokusebenza okulungiselelwe , i-Swift ikulungele ukuhlala ingenye yezilimi zokuhlela ezihamba phambili ohlelweni lwe-Apple.

5. Yiziphi izinsiza engingazisebenzisa ukuze ngifunde i-Swift?

Kunezinhlobonhlobo zezinsiza ezitholakalayo zokufunda i-Swift. Ezinye izinsiza ezinconyiwe zifaka:

• Imibhalo esemthethweni ye-Swift kuwebhusayithi ye-Apple: Umbhalo Osheshayo
• Izifundo eziku-inthanethi nezifundo ezinkundleni zemfundo ezifana ne-Udemy, Coursera ne-Pluralsight.
• Izincwadi ezikhethekile ku-Swift, njenge-Apple's "The Swift Programming Language."
• Imiphakathi eku-inthanethi nezinkundla lapho ungabuza khona imibuzo futhi uthole usizo kwabanye onjiniyela be-Swift.

Isiphetho Sesethulo se-Swift

Manje sesiqedile isingeniso sethu ku-Swift. I-Swift ishintshe indlela esithuthukisa ngayo izinhlelo zokusebenza zamadivayisi e-Apple. Ngohlelo lwayo oluqondakala kalula, ukuphepha okuthuthukisiwe, ukusebenza okuthuthukisiwe, kanye nokuhambisana kwezingxenyekazi eziningi, i-Swift inikeza ulwazi lokuthuthukiswa olusheshayo, olusebenza kahle, nolujabulisayo. Umphakathi wayo omkhulu kanye nokusekelwa kwe-Apple kuqinisekisa ukuthi ulimi luzoqhubeka luthuthuka futhi luthuthuke esikhathini esizayo . Uma unesifiso sokuthuthukisa izinhlelo zokusebenza zamadivayisi e-Apple, ukufunda i-Swift kuyisinyathelo esibalulekile sokusebenzisa ngokugcwele zonke izici nezinzuzo ezinikezwa yilolu limi .
