iOS 12 beta 5, seeded to developers yesterday, has strings of code that allude to support for a second SIM slot. This could possibly indicate plans for dual-SIM variants of future iPhones.
The second iOS 12 beta contains references to the next-generation Apple Watch such as the Watch4,1, Watch4,2, Watch4,3, and Watch4,4. The upcoming smartwatch is expected to launch in September.
