How to give a developer access without sharing passwords
Use team invites and limited roles instead of shared passwords, service by service, and know exactly how to remove access and rotate keys when the work ends.
ReadNative iOS apps are built in Xcode with Swift, using SwiftUI, UIKit or a mix, and older projects may still contain Objective-C. Dependencies come through Swift Package Manager or CocoaPods. Builds are signed with certificates and provisioning profiles tied to an Apple Developer account, then distributed through TestFlight and App Store Connect.
The app may not open in a current version of Xcode without fixes, because deprecated APIs, old Swift syntax or abandoned pods block the build. Apple periodically requires uploads to be built with a recent SDK, so an app that shipped once can find itself unable to ship an update. Signing assets may sit in a former contractor's account, and newer requirements such as privacy manifests for certain APIs and third-party SDKs may be missing.
Confirm that your company holds the Account Holder role in App Store Connect, not a former developer. List the minimum iOS version you want to support, the devices that matter, and any integrations such as Apple Pay, HealthKit or push notifications. Gather recent review messages if updates were rejected. The handover checklist generator helps you collect every account and credential owner before access is granted.

ReadA calm, ordered plan for the day your developer goes silent: protect the domain and email first, then hosting, code, data and money accounts.
ReadIn App Store Connect, open Users and Access and invite them with a role such as Developer or App Manager. The Account Holder role should stay with you or your company.
Not necessarily. UIKit is fully supported and SwiftUI can be added screen by screen. A rewrite is a business decision, not a requirement, so ask developers to explain the trade-off for your app.
