Besikhuluma izinyanga ezimbalwa ngezinsongo ezithunyelwe yi-Apple kubo bonke abathuthukisi namuhla abakazivumelanisi izicelo zabo nezinqubo ezingama-64-bit. Lezi zisongo ziphoqe onjiniyela ukuthi bavuselele izinhlelo zabo kuma-processor angama-64-bit, amaprosesa atholakala kuwo wonke amadivayisi we-Apple selokhu kwethulwe ama-iPhone 5s, cishe eminyakeni emine eyedlule. Sekuyiminyaka embalwa, i-Apple ixwayise bonke abasebenzisi abalanda uhlelo olungashintshelwanga kuma-processor angama-64-bit, ukuthi lo msebenzi ungahle ungahambi kahle futhi ungakhombisi amandla asinika wona.
Kepha kubonakala sengathi izinsongo ze-Apple zigcine seziqedile futhi sekuqalile ukususa izinhlelo zokusebenza ku-App Store namuhla ezingakashintshelwa kuma-processor angama-64-bit. Ngamahora ambalwa, ziningi izinhlelo zokusebenza eseziqale ukunyamalala, kwaqondana ngamahora ambalwa ngaphambi kokuqala kweWWDC 2017, umcimbi lapho i-Apple izokwethula khona i-iOS 11, inguqulo entsha yohlelo lokusebenza lwe-Apple lwamadivayisi eselula, kanye ne-tvOS, i-watchOS ne-macOS.
Izimpawu zokuqala zokuphela kwalokhu kutholakala zembulwa ngokukhishwa kwe-iOS 10.3, lapho i-iOS ibonise khona isexwayiso esithi lolu hlelo lokusebenza ngeke lisebenze ngezinguqulo ezizayo ze-iOS ngaphandle kokuthi i-Apple ibuyekeze uhlelo lokusebenza.
Lesi sinyathelo se-Apple kungenzeka yiba isiqinisekiso esisemthethweni sokuphela kokusekelwa kwe-iPhone 5 ne-5c, okuwukuphela kwamadivayisi emakethe ane-processor engu-32-bit futhi ahambisana nenguqulo yamanje ye-iOS 10, unyaka ngaphambili kunalokho obekufanele ukwenze, njengoba i-Apple isiqalile ukuyeka ukusekela amadivayisi angomakadebona njalo eminyakeni emibili.
IOS 7 bekunguqulo yokugcina ye-iOS etholwe yi-iPhone 4, i-iOS 9 bekunguqulo yokugcina ye-iOS etholwe yi-iPhone 4s, ngakho-ke inguqulo yakamuva ye-iOS ye-iPhone 5 no-5c kufanele kube yi-iOS 11, kepha njengoba sibona i-Apple kubonakala sengathi inciphise imigomo.
