3 I faced same issue. moving Headers in Target's build phase of the failed framework before compile sources fixed the issue. Example should look like: Dependencies Headers Compile Sources Link Binary With Libraries Copy Bundle Resources — jayantnd 3 months ago 2 Same issue for me with latest Xcode. I have Intel chip and no Headers — zwany 4/20/ · By default, Xcode typically uses the same number of threads as the number of cores in the machine’s CPU. However, you can dramatically reduce build times – in some instances by a full 30% – by increasing the thread count beyond the default. This takes advantage of processors’ ability to multi-thread or simulate additional cores Implicit dependencies if you list a target in your Link library With Binaries build phase, and Find Implicit Dependencies are enabled in the scheme editor (on by default), the build system will establish an implicit dependency on that target (even if it's not listed in target dependencies) Build phase dependencies each phase is a separate task

improve build performance, then you are at the right place. Reducing build times is super helpful for developers especially when you are working on decades-old legacy codebases with tons of dependencies.
Hence, in this article, I will try to list down all possible ways in which we can tweak our iOS project to elevate the performance of Xcode build. Foremost, we need to know how much time Xcode takes to build our project. Note 2: In order to have the correct build time displayed, please make sure to deep clean your project. Xcode 9 introduced a new build system I think it is called XCBuild internallywhich was only in its preview version.
But in Xcode 10, it is being used by default, and is written from scratch in Swift. The major goal of this new build system is to reduce the overall build time. Although this would not affect sample projects heavily, xcode target dependencies vs link binary with libraries, it will definitely have a drastic impact on a heavy-duty codebase.
Projects with legacy codebases and lots of dependencies would a great target. Do you see the difference? We care about build times mostly during development, which essentially takes most of our time. This is the default option in Xcode, although it is better to check it up, just in case. Notice the difference of 3. Else, you need to make sure that this setting is in place. You might be shocked to see the inverse effect here.
Since the compiler will omit the whole process of detecting the changed files internally, it would eventually save some time. This is very much required during the debugging phase. This will eventually reduce the build time as the compiler will omit the steps of attaching values to the debugger thread.
This displays a minor 0. This eventually saves a lot of time and hence, is one of the major reasons for people choosing Xcode target dependencies vs link binary with libraries over Cocoapods. When you have a project with dependencies managed by Cocoapods, every time the project is compiled, all sources of the dependencies are compiled, xcode target dependencies vs link binary with libraries.
It generates a framework and links it against the source project which is not compiled again during the build generation process. It should output an integer representing the number of cores your machine has:.
Bigger build machines like iMac with cores run the same build 3x faster than mine. So, basically, the number of cores in your machine plays a major role i. it is directly proportional to the build execution time. Keep in mind, though, that you may need to experiment to determine if there are diminishing returns for parallelized builds with your codebase, and then adjust the thread count accordingly.
Up next is a much simpler way of enabling parallel build execution. This is done from Xcode UI itself, which does this optimization automatically. Xcode compiler takes the project source and forms a tree-like structure to define the dependencies of modules.
It then goes compiling with a bottom-up approach i. compiling the modules with least dependencies first. In general, the Xcode project would have multiple dependencies on frameworks and other targets. Similarly, when the test target is executed, the compiler first makes sure that the app target is first executed. So dependencies play a major role in enabling the compiler to perform parallel build execution in the best possible way.
Although dependencies are internally identified by the compiler anyway, it is always better to have them placed in their execution order. This eventually helps the compiler to save time in rearranging dependencies internally during the build process.
For smaller hobby projects with no or fewer dependencies, the xcode target dependencies vs link binary with libraries is inverse i. parallel builds will actually increase build time. Another important trait with respect to ordering of dependencies is linking frameworks which we will see next. It is best to have the dependencies linked up manually in the Build Phases. Xcode allows us to identify blocks of code that are causing huge lags in compilation time.
You can specify a time limit for executing a block of code and let Xcode throw a warning for the code that xcode target dependencies vs link binary with libraries the specified time limit. So, after the build has been executed, Xcode will throw warnings for any function or expression that takes more than ms to get executed.
After adding these flags, whenever you build the project, Xcode should display warnings like this:. This is very helpful when you want to identify the functions or expressions that consume more time than expected. dSYM files are helpful during de-symbolication process of crash report files. The compiler takes time to produce the dSYM file. It makes sense to have it enabled only when Xcode debugger is not attached. So, it is better to have it disabled when we are running on the simulator.
This setting tells the compiler to omit the process of creating the dSYM file during the debug mode. This will eventually save the build time to a certain extent. With the advent of Swift, parts of legacy code bases got migrated to the latest language while some parts continued to be in Objective-C. This eventually lead developers to deal with interoperability in some way or the other.
These headers define the dependencies of files written in both languages. Changes to the header files drastically affects build time. For example, xcode target dependencies vs link binary with libraries, a small change in the Swift interface file enables the compiler to re-compile all the referenced Obj-C files and vice-a-versa.
You will then see some improvements over UITest case execution time. This literally means that it is nothing less than a real user using the app. Hence, it is always recommended to have the simulator settings to its minimum to have less usage of system resources. This will eventually fasten up test case execution and lead to less execution time overall. We saw a number of options to tweak in order to improve Xcode build performance.
Xcode does provide us with multiple combinations of configurable options but it is up to us to find out what amalgamation works and xcode target dependencies vs link binary with libraries best for a specific project. This, however, can be discovered only by testing out all the options trying to reach a suitable combination.
Certainly, you as a developer would have gone through most of the options already.
