Usage

// MARK: normal autoreleasepool
(0..<10000).forEach { _ in
    autoreleasepool {
        let imgView = UIImageView(frame: CGRectMake(0, 0, 5000, 5000))
        imgView.image = mockImage()
        imgView.image = nil
    }
}
XCTAssertEqual(arr1.count, 10000)

// MARK: autorelease and return value
var arr2 = [Int]()
(0..<10000).forEach { _ in
    let value = autoreleasepool { () -> Int in
        let imgView = UIImageView(frame: CGRectMake(0, 0, 5000, 5000))
        imgView.image = mockImage()
        imgView.image = nil
        return 1
    }
    arr2.append(value)
}
print(arr2.count)

// MARK: autorelease and return value?
var arr3 = [Int?]()
(0..<10000).forEach { index in
    let value = autoreleasepool { () -> Int? in
        let imgView = UIImageView(frame: CGRectMake(0, 0, 5000, 5000))
        imgView.image = mockImage()
        imgView.image = nil
        return (index % 2 == 0 ? nil : 1)
    }
    arr3.append(value)
}
print(arr3.count)

// MARK: autorelease with try
var arr4 = [Int]()
do {
    try (0..<10000).forEach { index in
        try autoreleasepool {
            if (index == 5000) {
                throw NSError(domain: "", code: 0, userInfo: nil)
            }
            let imgView = UIImageView(frame: CGRectMake(0, 0, 5000, 5000))
            imgView.image = mockImage()
            arr4.append(1)
            imgView.image = nil
        }
    }
} catch ( _) {

}
print(arr4.count)
