The reason is probably in the code above the loop. This condition is wrong: if($select == ‘Today’ OR ‘today’) { $select = $today; } … Read more

Here is a possible way: var letters: [Character] = [“a”, “b”, “c”, “d”] let insertionIndex = newArray[0] .index(newArray[0].startIndex, offsetBy: 5) for index in newArray.indices { newArray[index].insert(letters[index], at: insertionIndex) } And you could check the result this way: newArray.forEach { print($0) } Which prints: self.aButton.setTitle(“?”, for: .normal) self.bButton.setTitle(“?”, for: .normal) self.cButton.setTitle(“?”, for: .normal) self.dButton.setTitle(“?”, for: .normal) … Read more
Instead of using map on filtered you might wana use every instead: function filterYes(data, keys){ return data.filter(data => keys.every(key => data[key] === “yes”)); } I guess your data is an array (cause you call map on it) otherwise its a bit more complicated: function filterYes(data, key){ return Object.assign({}, …Object.entries(data).filter(([key, value]) => keys.every(key => value[key] === … Read more
You could do it for example: int negNumber = 0; int sum = 0; for (int i = 0; i < 3; ++i) { for (int j = 0; j < 3; ++j) { if (A[i][j] < 0) { ++negNumber; // increase negatives numbers found sum += A[i][j]; // add to our result the number … Read more
This can be done using cellfun and strsplit as follows: NewValues = cellfun(@(x) strsplit(x, ‘, ‘), MyValues, ‘UniformOutput’,0); NewValues = [NewValues{:}].’ 7 solved Split a value of different data types cell array based upon a delimiter

You need to check whether an array has an element or not. if addonCategory.count > 0 { // array has element } else { // array hasn’t element } Alternatively you can use guard let or if let to check. Using if let if let addonCategory = subCategoryModel[tappedIndex.section].items[tappedIndex.row].addonCategory, addonCategory.isEmpty { print(addonCategory) print(“Hello”) } else { … Read more
You could use reduce for this kind of thing, here is an example: var calendar = {Q1 : {P1 : {WK1 : {start: ‘1/1/2018’,end: ‘1/7/2018’},WK2 : {start: ‘1/8/2018’,end: ‘1/14/2018’}},P2 : {WK3 : {start: ‘1/15/2018’,end: ‘1/21/2018’}}},Q2 : {P3 : {WK5 : {start: ‘2/1/2018’,end: ‘2/7/2018’},WK6 : {start: ‘2/8/2018’,end: ‘2/14/2018’}},P4 : {WK7 : {start: ‘2/15/2018’,end: ‘2/21/2018’}}}}; var result … Read more

Keep products as structures: struct Product { let id: Int let quantity: Int let price: Double } then define array: internal static var productArray = [Product]() and add your products. let product = Product(id: 1, quantity: 99, price: 1.99) productArray.append(product) internal static prefix lets you to reach the array throughout the app. However, I don’t … Read more
