As per the official documentation of Swift, the configuration of URLCache.shared is
Memory capacity: 4 megabytes (4 * 1024 * 1024 bytes)
Disk capacity: 20 megabytes (20 * 1024 * 1024 bytes)
1. Now, what is the eviction policy used by URLCache.shared when the cache gets full? Is it LRU?
2. Suppose, there is a requirement to increase the cache size. Would increasing the disk capacity only suffice or is it required to increase the
memory capacity as well?
3. Is the cache size pre-allocated or does it grow as it is populated?
