It's essential to demonstrate that you can really go deep... there are plenty of followup questions and (sometimes tangential) angles to explore. There's a lot of Senior IOS Developer experts who've worked at DeliveryHero, who provide this sort of practice through mock interviews. There's a whole list of them curated on Prepfully. prepfully.com/practice-interviews Less

Loop half size of the array exchanging element i with element (size-i-1). If array size is odd number than half is (size -1)/2. However, you can just do size/2 -- integer division would give above, so 15/2 = 7. Less

Using CoreLocation we can calculate the time taken from one point to the second point. In core location with each location point we have the time stamp as well. Using this time stamp we can calculate the speed of the object. Less
