Adding Firestore to a Flutter project for iOS can significantly slow down builds because the Firestore library heavily depends on an extensive C++ codebase. When CocoaPods downloads and compiles Firestore from source code, it includes that entire C++ base and triggers costly compilation processes that increase total build time.
The problem lies in the fact that the default version many pods use requires converting and compiling the C++ code in each new environment or when precompiled binaries are not available. That conversion consumes CPU, memory, and time, and in development and CI environments it is especially noticeable when compiling for simulators and iOS devices.
An effective solution is to use precompiled versions of the Firestore library. By linking a precompiled version with the pods, the C++ code compilation process is skipped, drastically reducing build times. Firebase distributes binaries and xcframeworks in its most recent releases that allow integrating Firestore without compiling from scratch.
Other strategies to minimize the impact on Flutter iOS builds include migrating the CocoaPods integration to Swift Package Manager when possible, enabling the use of binary frameworks instead of sources, and leveraging caches in CI for DerivedData and precompiled pods. It also helps to keep the Firebase SDK updated to benefit from improvements in binary distribution and xcframeworks compatibility.
Practical tips for Flutter developers and iOS teams: 1 Take the path of precompiled binaries or Firebase xcframeworks for Firestore. 2 Set up persistent cache for DerivedData and pods in CI. 3 Avoid unnecessary recompilations by excluding architectures not used in the local build or CI runner. 4 Update Firebase regularly and review release notes for changes in binary distribution.
