Swift’s foundation library provides a sorted(by:) function for sorting arrays. The areInIncreasingOrder closure needs to return true if the closure’s arguments are increasing, false otherwise. How to use the closure for sorting by multiple criteria? Let’s take a look at an example of sorting an array of Player structs. Sort by score in descending order […]
Benelec has designed and manufactured a mature range of high-performance: 2 & 4 Stack UHF Omnidirectional Base Antenna Arrays. These are broadband antennas covering the popular UHF frequency bands: 380-490MHz, 400-520MHz. These models have a patented configuration providing the most even omni-directional radiation pattern greatly enhancing a site’s coverage. The antennas are rated at 500w […]
