iOS - 'MyProject-Swift.h' file not found when running Unit Tests for Swift
header, ios, swift, unit-testing
Solution
"MyProject-Swift.h" file is generated at following path:
`"$(TARGET_TEMP_DIR)/../$(PROJECT_NAME).build/DerivedSources"`
I end up adding this to Header Search Paths for my Unit Test target.
Also as @hyouuu pointed out about being the known issue, hopefully Apple will provide some good solution at their end. Until I believe we need to use this above solution.

Problem
I am trying to setup Unit Testing for my project. It is an existing Objective-C app, that I have recently added one Swift class to. I have setup the 'MyProject-Swift.h' and Swift Bridging files (both 'MyProject' and 'MyProjectTest') and I am able to build and run the app just fine using both Objective-C and Swift code. However, now I want to run some Unit Tests on the new Swift class. I setup my test file and it looks like the following: MySwiftClassTests.swift: ``` import UIKit import XCTest import MyProject class MySwiftClassTests: XCTestCase { override func setUp() { super.setUp() // Put setup code here. This method is called before the invocation of each test method in the class. } override func tearDown() { // Put teardown code here. This method is called after the invocation of each test method in the class. super.tearDown() } func testExample() { // This is an example of a functional test case. XCTAssert(true, "Pass") } func testPerformanceExample() { // This is an example of a performance test case. self.measureBlock() { // Put the code you want to measure the time of here. } } } ``` I get this error when running the app as Test: ``` 'MyProject-Swift.h' file not found ``` I am not sure why this happens only when trying to run the Tests. Any suggestions?
