Kanye ne-iOS 8.3 beta 1, i-Apple ikhishwe i-Xcode 6.3 beta 1 ngohlobo olusha lweSwift, ulimi lwayo lokuhlela i-Cocoa ne-Cocoa Touch olusetshenziswa ngabathuthukisi ukudala izinhlelo zokusebenza ku-iPhone, i-iPad, i-iPod touch ne-Mac. 2014 futhi ivuselelwa kunguqulo 1.2.
I-Xcode 6.3 ifaka uhlobo olusha lolimi lweSwift, ifaka nezinguquko eziningi zolimi ezichazwe kokusha ku-Xcode 6.3 beta. I-Xcode 6.3 ibuye inikeze ngethuluzi lokufuduka lokuvumelanisa ikhodi yakho ne-Swift 1.2.
Lona inguqulo entsha ye- swift Ukuvuselelwa kuchazwa njenge- "enkulu" ngolimi lohlelo nazo zonke izinguquko ezigqanyisiwe kufayela le- I-Apple blog enikezelwe kuSwift. Ngenyanga edlule, iStanford University ishicilele inkambo yayo ye-iTunes U ekuthuthukisweni kwesicelo isebenzisa ulimi lwezinhlelo lwe-Apple's Swift, ngokuthuthuka okuningi komhlanganisi, iSwift 1.2 yenzelwe ukuzinza nokuthuthukisa ukusebenza kuzo zonke izinzwa. Lezi zinguquko futhi zinikeza umuzwa ongcono lapho usebenza neSwift kuXcode. Okunye ukuthuthuka okubonakala kakhulu kufaka isibonelo:
- Ukwakhiwa okuqhubekayo nezibuyekezo (Ukwakhiwa okwandayo): Amafayela womthombo angashintshile ngeke ahlanganiswe kabusha ngokuzenzakalela.
- Ukuphumelela okusheshayo: Izinguqulo zokususa amaphutha zikhiqiza ama-binaries asebenza ngokushesha okukhulu, futhi ukulungiselelwa okusha kunikeza ukusebenza kwenguqulo engcono kakhulu.
- Ukuxilongwa okungcono komhlanganisi: Iphutha elicacile nemilayezo yesexwayiso, kanye ne-Fix-it entsha, yenza kube lula ukubhala ikhodi kahle ku-Swift 1.2.
- Ukuthuthuka kokuqina: Iziphazamisi ezihlanganisa kakhulu ezihlanganisiwe zilungisiwe ngezixwayiso ezimbalwa ezivela eSourceKit ngaphakathi kwesihleli seXcode.
Kubalulekile futhi qaphela ukuthi ku = Swift 1.2, lolu limi luye lwahlanjululwa ngokuqhubekayo ukuze kuqinisekiswe ukuziphatha okulindelekile nokuzinzile, ngezithuthukisi ezahlukahlukene ekusebenzisaneni phakathi kweSwift neNhloso-C.
