Common Mistakes

Using a number without quotes.

Setting deployment target lower than supported by Flutter.

Common Mistakes

Using lowercase 'release' instead of 'Release'.

Common Mistakes

Using development identity for release builds.

Leaving provisioning profile as 'Automatic' when manual is required.

For release builds, the CODE_SIGN_IDENTITY should be "iPhone Distribution" and the PROVISIONING_PROFILE_SPECIFIER should match your distribution provisioning profile name.

Common Mistakes

Using 'dev' flavor when intending production.
