# 2024 Deprecation Note for iOS service versions
Release Date: 2024-08-07
# Deprecated root cause
Below versions are deprecated by "App is resigned" error in Testflight. To fix this error, new versions are released as hotfix. Also, 1.9.0.0 and 1.9.0.0 versions are deprecated to avoid false-positive errors in Anti-swizzling detection. We will upgrade a new version with controllable anti-swizzling detection feature.
