Question

this is done in swift playgrounds, these are two separate questions but using same info, i dont really know how to approach it. what i have just makes it keep printing and neve stop. and help is appreciated

You may want your fitness tracking app to help runners track and improve their cadence. Running cadence is the number of steps a runner takes in a minute. To help with this, you decide to let the user input a cadence, after which your app will play a sound at each interval they need to take another step.

For this exercise, you'll simulate a "test run" of the cadence feature of your app. Use a while loop to print "Take a step" to the console 10 times. Once you've successfully printed "Take a step" to the console 10 times, add the following code to the end of your while loop: Thread.sleep(forTimeInterval: 60/cadence). This will put a pause between each itertion of the while loop so that the print statements actually occur at the proper cadence.

let cadence: Double = 180

var testSteps = 0

//while testSteps < 10 {

// takeSteps += 1

// print("Take a Step.")

//}

Recreate the above cadence example using a repeat-while loop.

testSteps = 0

Explanation / Answer

Below code is written in such way that it never stops and prints Take a step 10 times to the console. After that sleeps for few seconds and again starts.

Code:

let cadence: Double = 180
var testSteps = 0
while true {
while testSteps < 10 {
testSteps += 1
print("Take a Step.")
}
Thread.sleep(forTimeInterval: 60/cadence)
testSteps = 0
}
