Answer 1

您的问题出在内循环中，特别是在：

for testing1 in (0...refLat.count).reversed()

那将迭代一个比refLat更多的值，你想要的是：

for testing1 in (0..<refLat.count).reversed()

但一般情况下，您可以直接使用for循环生成的索引来简化代码，因此不要管理自己的counterR和counterS，而是让for循环执行它适合你：

// counterS will be generated and managed by the for loop
for counterS in (0..<sampLat.count) {

    let coordinates = CLLocation(latitude:sampLat[counterS], longitude:sampLong[counterS])

    // same for counterR
    for counterR in (0..<refLat.count).reversed()
    {

        let coordinates2 = CLLocation(latitude:refLat[counterR], longitude:refLong[counterR])

        let distanceInMeters = coordinates.distance(from: coordinates2)

        // I will use string interpolation
        print("distance found - \(distanceInMeters)")

        print("Counter Reference - \(counterR)")

        if distanceInMeters <= 50 {
            print("crossed check point for - \(counterR)")
        } else {
            print("out of range")
        }
        print("---------------------------------------")
    }

    print("Counter Sample \(testing)")
    print("******************************************")
