iOS interviews test Swift depth, memory and ARC, app lifecycle, and behaviour on a constrained device.

The short version
Why the Ios Engineer interview is hard
iOS interviews reward candidates who understand what the device is doing. Swift language depth, memory under ARC, app lifecycle and the constraints of running on a phone come up consistently.
What to expect
The rounds you should rehearse
Memory and ARC
retain cycles, weak and unowned, and why a screen never deallocates.
App lifecycle
state restoration, backgrounding, and being terminated without warning.
UIKit and SwiftUI
knowing where each fits and how they coexist in real codebases.
Avoid these
The mistakes that quietly sink candidates
Writing Swift without being able to explain when a retain cycle occurs.
Ignoring the lifecycle, then having no answer for what happens when the app is backgrounded.
Treating battery, memory and network constraints as someone else's concern.
Reading the questions is not practicing them.
Run a live voice mock tuned to the Ios Engineer interview. It follows your answers, probes the gaps, and scores you like a senior interviewer would.
