I'm making a simple Word Builder type of game (where one player enters a word, and the other player enters a word starting with the last letter of the first player's word), and I can't get the Text to show up on both the screens. I'm able to get the text to show up if I hard code it, like:

When executing directly, everything works as expected:

I have spatio-temporal data for shrub colonisation, due to a very high number of individuals restricted to three polygonal transects (5m wide, 60-100m long, spaced ~30m apart). I am analysing the data in 'spatstat' version 1.58-2.

I want to assess the clustering between individuals, both total (all mapped individuals) and in subsequent cohorts (recruits vs. established in 7 subsequent periods), by 'pcfinhom' & 'pcfcross.inhom'. I have created 'envelope'-objects with arguments 'savefuns = T' and 'savepatterns = T' for latter assessment by DCLF-test, for example:

T_all_PCFi_gl<-envelope(T_all_ppp,fun=pcfinhom,nsim=39,verbose=T, simulate=expression(rpoispp(den_tr[["T_all"]])), #density in all transects correction="trans",global=T, savefuns = T, savepatterns = T)

However, if I want to check the results by the DCLF-test,

I have created a component that allows users to select objects from a list and put them into another "selected list" lets say. So there are 100 items in the main list and however many in the users selected list. They can of course remove and add items as they want.

There are two buttons at the bottom of the modal. Cancel and Update. Where Cancel forgets anything they have added or removed (essentially an Undo of when they popped up the modal) and Update technically does nothing because when you are adding and removing, I am actually updating the real selected list.

So my data has these two properties (among others of course):

Being the Swift noob that I am, I find myself copying and pasting code. I know I'm supposed to use the DRY method and not do this, but this particular bit of code has me stumped. I tried creating a struct to hold it, but the struct threw all sorts of errors. I don't quite understand classes and how I would subclass it, and so maybe that's the solution. I just don't know how to do it? Or maybe an extension?

Anyway, here is the code I keep copying and pasting in each new view controller:

I am trying to write my Cucumber tests using TypScript, like this:

I am trying to implement a word game, where a user types a letter on a board to form a meaningful word and submitt it, if the typed word is present in a JSON file, the user gets a point. So I have implemented the basics of the game, but unfortunately I have found that my linear algorithm is inefficient to traverse about 400k words in the JSON file. So my question is what kind of algorithm I can write to make it efficient? My interface looks like this. Letters appear randomly on the board.

A tiny part of my JSON file look like this

I am generating all possible combinations for the given scrambled letters and storing it in a list. Then, I'm checking if words from that list are in my database. Although, the word is in the database, it is not returning so.

example for result list:

I know I'm missing something simple, but I've spent hours trying to figure it out. All my code works and runs fine except there is no image. It is blank. Why?
